Description

[0002] An electronic atomization apparatus uses electricity to heat and atomize liquid, and is currently commonly used in the field of electronic atomizers. Electronic atomizers have become popular these years as a new tobacco product due to their cigarette-like experience. The atomization core, as the core of the e-cigarette, plays a key role. The process of atomization is primarily determined by several factors: the amount of air entering and the entry path thereof during atomization, commonly known as the air path, and the location of entry of oil, the amount of oil entering, and the length of the oil entry path, commonly known as the oil path, and also the influence of the heating circuit, which is an electrical circuit. Furthermore, as the liquid is consumed, the air pressure in the oil compartment decreases, leading to unsmooth liquid flow, and there is also a concern about ventilation. Often, changes or mismatches in any of the parameters can lead to poor effect of atomization, resulting in various problems. Due to the need to meet the needs of consumer groups in different regions, the outside appearance varies greatly, and with these variations, the internal structure also changes, and thus, the atomization parameters are often changed. Therefore, it is necessary to provide a modular atomization apparatus, which is made in a simple package form for the air path, the oil path, the electrical circuit, and ventilation on the module, so as to meet the needs of more users, and allow the atomization apparatus to ensure the atomization effect by simply using this atomization module.SUMMARY OF THE INVENTIONTechnical Problems

[0028] FIGS. 1-10 shows an atomization module according to some preferred embodiments of the present invention, comprising a support 1, a liquid guide body 2, a heating body 3, a sealing gasket 4, and a base 5. The support 1 is made of plastic, ceramic or metal and can be manufactured through a mold batch molding process. In order to facilitate matching with various liquid storage tanks, the shape of the support 1 is generally columnar, and a cylindrical structure is preferably used. The support 1 is open from top to bottom and is provided, in the interior thereof, with a mounting bin 11. The arrangement of the support 1 plays a role of supporting and a role of encapsulating the liquid guide body 2 and the heating body 3. The liquid guide body 2, the heating body 3, and the sealing gasket 4 are all arranged in the mounting bin 11. The heating body 3 is attached to the bottom of the liquid guide body 2. The liquid guide body 2 functions to conduct liquid to the heating body 3, and the heating body 3 functions to heat and atomize the liquid. The sealing gasket 4 is arranged between the support 1 and the liquid guide body 2 and functions to seal the liquid guide body 2 and the support 1 to prevent liquid leakage. The base 5 is arranged in a bottom open end of the support 1 to encapsulate the bottom of the support 1.

[0029] Further, as shown in FIG. 3, the support has a columnar structure. The mounting bin 11 transversely penetrates two side walls of the support 1 to form a first liquid inlet 12. The first liquid inlet 12 and the liquid guide body 2 are in communication with each other to form a liquid inlet channel A. Atomizable liquid in an oil storage bin may pass through the first liquid inlet 12 to get into the mounting bin 11 of the support 1 to be conducted to the liquid guide body 2 and atomized by the heating body 3. As shown in FIGS. 4 and 8, an airflow gap 19 is formed between the mounting bin 11 and an outer wall of the support 1. The mounting bin 11 divides the support 1 into two portions - upper and lower portions, and the lower portion is formed with an accommodating groove 13 arranged in a direction facing the base 5. The sealing gasket 4 is received in and contacts the accommodating groove 13, and the liquid guide body 2 abuts the sealing gasket 4. The side of the support 1 where the accommodating groove 13 is arranged is the air inlet end, and the other side is the mist outlet end. The air inlet end, the airflow gap 19 and the mist outlet end are in communication with each other to define an airflow channel B. External air enters the support 1 from the air inlet end, and mixes with atomized gas in the interior of the mounting bin 11 to form aerosol. The aerosol is discharged through the mist outlet end. The base 5 is arranged in the air inlet end. The base 5 is formed with an air inlet opening 51. External air enters the support 1 from the air inlet opening, and mixes with the atomized gas in the interior of the mounting bin 11 to form the aerosol, which is discharged through the mist outlet end.

[0030] As shown in FIGS. 5 and 7-8, the side of the mounting bin 11 facing the base 5 is provided with the accommodating groove 13 and a ventilation groove 14 in communication with the accommodating groove 13. The accommodating groove 13 matches with the sealing gasket 4, and the sealing gasket 4 is received in and contacts the accommodating groove 13 to seal the liquid guide body 2 and the support 1. The groove depth of the ventilation groove 14 is greater than the groove depth of the accommodating groove 13, so that a gap is formed between a top surface of the sealing gasket 4 and the groove depth of the sealing gasket 4, and the ventilation groove 14 is in communication with the first liquid inlet 12. The liquid guide body 2, the ventilation groove 14, and the first liquid inlet 12 are in communication with one another to form a ventilation channel C. This arrangement makes it difficult for the atomizable liquid to be leaked from the ventilation groove 14 due to the force of capillary phenomenon, and when the air pressure in the oil storage bin is excessively low, gas in the mounting bin 11 can move into the oil storage bin from the ventilation groove 14, in order to prevent unsmooth liquid conducting caused by lowering of the air pressure in the oil storage bin resulting from consumption of the atomizable liquid, therefore avoiding problems such as dry burning and improving the atomization experience.

[0031] The present invention provides an atomization module, which provides, by means of exterior encapsulation, the atomization module with an external shape that is relatively easy to assemble, and includes, in the interior, stable liquid inlet channel A, airflow channel B, ventilation channel C, and circuit, so that the atomization module can be used once inserted into an oil storage bin; the present invention has a high degree of integration and requires only an oil storage bin on the exterior thereof; the present invention provides strong universality and is applicable to the atomizer structures of various oil storage bins, simplifying the development of products of electronic atomizers; subsequent assembly with the oil storage bin is simple and easy. The modularization is conducive to large-scale and large-batch production; and by setting a ventilation groove 14 in communication with the accommodating groove 13, the groove depth of the ventilation groove 14 being greater than the groove depth of the accommodating groove 13, and the ventilation groove 14 and the liquid inlet opening being in communication, the liquid guide body 2, the ventilation groove 14, and the first liquid inlet 12 are in communication with one another to form the ventilation channel C, making the atomizable liquid difficult to leak from the ventilation groove 14 due to the force of capillary phenomenon, and when the air pressure in the oil storage bin is excessively low, gas in the mounting bin 11 can move into the oil storage bin from the ventilation groove 14, in order to prevent unsmooth liquid conducting caused by lowering of the air pressure in the oil storage bin resulting from consumption of the atomizable liquid, therefore avoiding problems such as dry burning and improving the atomization experience.

[0032] Further, in some preferred embodiments, as shown in FIGS. 8-9, the ventilation groove 14 comprises a first ventilation groove 141 and a second ventilation groove 142 in communication with the first ventilation groove 141. The first ventilation groove 141 is set away from the accommodating groove 13, and the second ventilation groove 142 is set on the accommodating groove 13 and in communication with the first liquid inlet 12. It is appreciated that the sealing gasket 4 contacts and abuts the accommodating groove 13, while also covering a part of the second ventilation groove 142. A certain distance is present between the top surface of the sealing gasket 4 and the groove depth of the second ventilation groove 142. The second ventilation groove 142 and the first liquid inlet 12 are in communication with each other, so that the atomizable liquid is not easy to leak from the second ventilation groove 142 due to a combined effect of the force of capillary phenomenon and the sealing gasket 4. When the air pressure in the oil storage bin is excessively low, gas in the mounting bin 11 can move in the first ventilation groove 141 to the second ventilation groove 142, and passes through the second ventilation groove 142 to the first liquid inlet 12 to finally enter the oil storage bin, in order to prevent unsmooth liquid conducting caused by lowering of the air pressure in the oil storage bin resulting from consumption of the atomizable liquid, thus avoiding problems such as dry burning and improving the atomization experience.

[0033] Further, in some preferred embodiments, the distance from the plane where the top surface of the sealing gasket 4 is located to the plane where the groove bottom of the second ventilation groove 142 is located is 0.1-0.6mm. This distance is sufficiently small, so that the atomizable liquid is not easy to leak from the second ventilation groove 142 due to a combined effect of the force of capillary phenomenon and the sealing gasket 4. When the air pressure in the oil storage bin is excessively low, gas can move from the first ventilation groove 141 through the second ventilation groove 142 to enter the oil storage bin, preventing unsmooth liquid conducting caused by lowering of the air pressure in the oil storage bin resulting from consumption of the atomizable liquid.

[0034] Further, in some preferred embodiments, as shown in FIGS. 3-8, a circle of circumferential flange 15 is provided on an inner wall of the support 1 toward the center of the support 1, and an inner wall of the circumferential flange 15 encloses and defines a second liquid inlet 16. The first liquid inlet 12 and the second liquid inlet 16 are in communication with each other. The circumferential flange 15 and a lower inner wall of the support 1 define the mounting bin 11. The accommodating groove 13 is formed on the circumferential flange 15. The top surface of the sealing gasket 4 and the circumferential flange 15 are in contact with each other.

[0035] Further, in some preferred embodiments, as shown in FIG. 3, the support 1 is provided with a flow guide portion 17 extending from an upper wall of the first liquid inlet 12 in a direction toward the second liquid inlet 16, such that the cross-sectional area from the first liquid inlet 12 to the second liquid inlet 16 gradually decreases in a direction approaching the central axis of the support 1. This arrangement achieves an effect of effectively guiding and converging flow, avoiding the occupation of internal space while ensuring sufficient flow supply, thereby making the overall structure more compact. Furthermore, the flow guide portion 17 that is arranged inclinedly facilitates the quicker arrival of bubbles of ventilation in the oil storage bin, preventing bubbles from accumulating there and blocking liquid entry.

[0036] Further, in some preferred embodiments, the first liquid inlet 12 is at least symmetrically arranged on the side wall of the support 1, and correspondingly, the flow guide portion 17 is at least symmetrically arranged, so as to speed up the liquid inlet rate and ensure uniform liquid inlet.

[0037] Further, in some preferred embodiments, as shown in FIGS. 2-3, the sealing gasket 4 is formed with a liquid guide opening 41, and the liquid guide opening 41 and the second liquid inlet 16 are in communication with each other. The liquid guide opening 41 is arranged corresponding to a liquid inlet surface 23 of the liquid guide body 2, so that the liquid entering the second liquid inlet 16 passes through the liquid guide opening 41 to enter the liquid guide body 2.

[0038] Further, in some preferred embodiments, as shown in FIGS. 7-9, the mounting bin 11 is further provided therein with limiting portions 18. The limiting portions 18 are multiple limiting portions 18 with a porous structure arranged along edges of the accommodating groove 13. The limiting portions 18 are in contact with the liquid guide body 2 and the support 1. The plane where the bottom of the liquid guide body 2 is located in higher than the plane where the bottom of the limiting portion 18 is located. The arrangement of the limiting portion 18 provides, on the one hand, an effect of positioning and limiting, so that during mounting of the liquid guide body 2, the liquid guide body 2 can be quickly mounted to the mounting position and the liquid guide body 2 is prevented from being shifted by an external force; on the other hand, the limiting portion 18 also provides an effect of gathering condensed liquid, wherein the atomizable liquid forms atomized gas after being vaporized, and the atomized gas is mixed with air to form aerosol, and the aerosol, upon cooling, forms the condensed liquid, where when a portion of the condensed liquid excessively gathers on the inner wall of the support 1, the condensed liquid can be locked by the capillary action of the limiting portion 18, and then transferred to the liquid guide body 2 to be heated and atomized by the heating body 3 for the second time for use, thereby further preventing the leakage of the condensed liquid while improving the utilization rate of the atomizable liquid.

[0039] Further, in some preferred embodiments, as shown in FIG. 3, the top surface of the liquid guide body 2 is formed with a liquid storage reservoir 21 facing the liquid guide opening 41. The liquid storage reservoir 21 and the liquid guide opening 41 are in communication with each other. The inner wall of the liquid storage reservoir 21 forms a liquid inlet surface 23. the liquid guide body 2 comprises the liquid inlet surface 23 and an atomization surface 22 opposite to and facing away from the liquid inlet surface 23. The heating body 3 is attached to the atomization surface 22. The liquid storage reservoir 21 absorbs and collects the atomizable liquid that moves in through the first liquid inlet 12 and is conducted to the atomization surface 22 through the liquid inlet surface 23 to be heated and atomized by the heating body 3. The upper surface of the liquid guide body 2 is shaped to match the sealing gasket 4, and is preferably a plane extending along a cross-sectional surface of the sealing gasket 4.

[0040] Further, in some preferred embodiments, the liquid guide body 2 has a porous structure. The liquid guide body 2 can be made of a material with capillary channels or pores, such as fiber cotton, porous ceramics, glass fiber wire, porous glass ceramics, porous glass, and other hard or rigid capillary structures. The pore size of the micropores in the liquid guide body 2 is 0.2 microns to 200 microns. The micropores have an effect of conducting the atomizable liquid, and also, the micropores are small so as to form an oil film, which, combined with an effect of negative pressure, can hold liquid in the oil storage bin, making the liquid less likely to drip.

[0041] Further, in some preferred embodiments, as shown in FIGS. 1-6, the atomization module further comprises external connection electrodes 6. The base 5 is formed with electrode apertures 52. The heating body 3 comprises a heating circuit 31 and electrode connection members 32 arranged to extend from two sides of the heating circuit 31. The external connection electrodes 6 extend through the electrode apertures 52 to electrically connect with the electrode connection members 32. The heating body 3 can be formed on the atomization surface 22 of the liquid guide body 2 by attaching, printing, deposition, and the like. The heating body 3 can be made of a material such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, metal titanium, conductive metal fiber filaments, conductive carbon fiber filaments, and conductive graphite filaments. The heating circuit 31 can be a conductive track with a pattern such as winding and circuitous patterns and has two ends on which the electrode connection members 32 are arranged. The electrode connection members 32 can be in the form of pads, or can also be in the form of leads. The electrode connection member 32 and the external connection electrodes 6 are electrically connected to each other so that a power supply device can supply electrical power to the atomization module.

[0042] Further, in some preferred embodiments, the support 1 has a columnar structure. In order to facilitate matching with various types of oil storage bin, the support 1 is columnar in shape, and a cylindrical structure is preferred. This simplifies the development of final products of electronic devices, and the assembly with the oil storage bin is simple and easy, which is conducive to large-scale and large-scale production.

[0043] The present invention also provides an atomization apparatus, which, as shown in FIGS. 10-13, comprises the atomization assembly described above and an oil storage bin assembly 200.

The support 1 of the atomization module 100 is inserted into the air guide tube 10 or sleeved on the outside of the air guide tube 10 by way of the mounting position 81. Before use, the atomization module 100 is partially exposed outside the bottom plug 8, and the first liquid inlet 12 of the atomization module 100 is blocked by the inner wall of the bottom plug 8. It is appreciated that the oil storage bin 9 stores therein atomizable liquid, and before use, the liquid guide body 2 is not in contact with the atomizable liquid, and the first liquid inlet 12 of the atomization module 100 is blocked by the sealing part of the oil storage bin assembly 200. At this time, the atomizable liquid is in a state of not contacting the liquid guide body 2. To use, the atomization module 100 is pushed into the oil storage bin assembly 200, until the base 5 of the atomization module 100 is flush or basically flush with the bottom of the bottom plug 8, and the first liquid inlet 12 is exposed in the oil storage bin 9. The atomizable liquid in the oil storage bin 9, being acted by the gravity, flows into the first liquid inlet 12 of the atomization module 100. This arrangement is conducive to transportation, can ensure that the atomizable liquid will not leak during transportation, and can avoid the problem of the heating body 3 being corroded resulting from long-term contact between the liquid guide body 2 and the heating body 3 on the liquid guide body 2 during storage.
